A quick trip to Bangkok and you’ll notice that it's a fashion-conscious city for pretty much every stratum of society, from your cafe hipster to your mall-going teen and, of course, its royal family.

For her latest autumn/winter collection, the princess took elegance to a new level with 34 looks – seven of which were part of her menswear collection S’Homme – adorned with jewellery from her Sirivannavari Bijoux line for a complete look. The princess does not skimp on the details.

On the catwalk, there was a strong showing of tweed and houndstooth suits, cape coats and Napoleonic jackets. Gingham skirts nodded to European heritage, while the vibrant colours, embellishment, finishing and sense of abundance was very much Thai.

The collection was undoubtedly for a jet-setting woman who can leave the country's tropical climates for an actual winter destination requiring layers. There is also a sense of evening wear sophistication with the well-structured suits, jackets and skirts made from densely woven fabrics like brocade contrasted with metallic, vibrant silk. It has holiday party written all over it, especially the dress with a strapless bodice constructed with a juxtaposing electric pink graphic print for the top half, and a dark gingham fabric for the bottom half. It’s both youthful and chic.

For a more mature approach, Sirivannavari offers a series of caped looks with variegated colours, which goes over a sexy sheen dress with a twist front. The princess knows how to churn out a tasteful revealing look, as she does with something more covered up like her long tailored suit jacket in white brocade over a metallic taupe blouse and wide pant. The collection mixes British prep-school with a Hugh Hefner sense of bon vivant style, punctuated by high femme as exemplified by the asymmetrical LBD with a serpentine feather accent running across the length of the piece.

The men's collection follows a similar thread as its counterpart with a mix of sophistication and edgy pieces, such as the pleater double-breasted jacket mixed with structured woven pants. Or for something more colourful, the tangerine-lined gingham trench coat with stripe knit sweatpants. It's a bit highbrow streetwear – which any good luxury brand needs to lean into these days.
